It's probably worth mentioning that I'm not asking for the SCP itself to be reviewed here, just the tone. That said, if you do wish to give any advice on if it's any good, if it can be improved, etc., then it would be appreciated nonetheless.

You have some serious issues with the tone and science in this article. The ones that stick out to me:

The Containment Procedures are inconsistent with normal SCP articles, and something irks me about the whole 'technicians are allowed to access it' even though it's not explicit open-access.

You are being way too wordy in the Description block; you don't need that much text to describe what is ultimately an extremely simple SCP.

You don't need x500 magnification to read a circuit board… in fact, you can read off a circuit board with your naked eye so long as you're trained. If you need that much magnification, it's an integrated circuit, and you'd have to disassemble it to see the circuitry anyways.

At the end of the article, the SCP appears to be broken. That would imply that it's Neutralized.

Additionally, it will never pass through an object; for example, if the button is pressed with the motorcycle 5 metres away from a wall, it will never appear on the other side of the wall. When pressed while SCP-XXXX (with SCP-XXXX-2 attached) is in motion however, it will cause the motorcycle to jump in the direction of travel the full range of 12 metres in every test, even through walls, suggesting that the engine’s presence plays a part in its correct function.
